McCain applied Liquigro's Ammonium Orthophosphate on 12 potato trial sites by spraying on top of the plants.

The Netherlands experienced it's worst drought in recent history and the potatoes died 50 days too early.

Taking above into account, Liquigro achieved the following results, made available by McCain:

On the first 6 trial sites, Liquigro achieved a 37.6% increased yield,against the controls. Liquigro also produced the best quality potatoes. Liquigro achieved an average of 64.1 t/ha, compared to the McCain controls of 46.6 t/ha.

An additional 1,103.20 euros (R16 360) was generated by Liquigro's trial, against the controls, after expenses.
